The Zero mission where gotta fly the fucknig mini copter and kill 5 couriers, then take it back. This thing fucking sucks, I've been trying the past two hours to do it, but I can't. Closest I got was killing all five then running out of gas before I could get back. Rockstar, why the fuck did you put these gay ass missions in the game? They are worthless.
Anyone got good strategies on beating this mission. I've tried various combinations of who to take out first and who not to, but it seems completely on luck if you beat this mission or not depending which way the couriers move to, so you have enough gas to beat the damn mission. SHIT.
Well, the first thing you need to do is get used to flying the plane. The controls are VERY loose, so whenever you need to make a course correction, do it very gently. If you just start yanking the stick all over the place, you're going to end up spinning out of control and most likely plowing into the ground.
The next thing you should keep in mind is that the fuel meter isn't really a fuel meter, but more of a timer. From what I've read, it only stops decreasing if you're at a dead standstill, but otherwise it runs down at a constant rate. So don't think that by taking it easy on the speed you'll be saving gas or anything.
The second most important factor in completing the mission (aside from having a good handle on the controls) is to take out the targets in the correct order. The couriers always start in the same position, and tend to hang around their starting area. The first one you want to take out is right in front of the building you start on top of. Just take off and start shooting at him. For the first van, you'll actually want to start shooting from a distance, since as soon as the van starts getting hit, the driver will jump out. You don't need to take out the vehicles, only the drivers.
As soon as you've taken out the first driver, your instinct may be to turn left and take out the blip that's pretty close to your current position. Don't do it.
If you took out the first target quickly enough, you should still be going straight from your initial takeoff path. If you look at your radar, there'll be another blip ahead of you a ways. Head towards that one. It's another van, but the driver won't get out when you start shooting, which means that you have to blow the van up. This is where knowing how to handle the plane comes in handy, as you'll have to be pretty precise. I don't remember if this van shoots back at you or not, but he'll definitely run as soon as he starts getting hit. This is key, as you can just land right behind him and unload the machine guns into the back of the van. If you're lucky, this will blow it up before he can make a run for it. Make sure that you didn't land too close to the van, otherwise you're going to get taken out in the explosion.
Next, head back towards the other blip that was closest to the starting point. It's just a guy on a bike, who should go down pretty easily.
Finally, you need to make the looong journey north to take out the last two blips. One of these is another van, and the other is two guys on a Sanchez. Both targets will shoot at you as soon as you start shooting at them. For the van, just come in close behind it and unload into the rear. It won't be able to return fire, as it shoots from the side windows.
The two guys on the Sanchez is the hardest one, as they can hit you no matter where you are. Like with the last two vans, just get in really close and fire away. Once you see them start to go up in flames, get the heck out of there. They still take a few seconds to finally explode, and they'll be shooting at you the whole time. Quite a few of my attempts at this mission ended with me with plenty of fuel left, and I got taken out by the Sanchez right before it blew.
If you did the order right, and took the targets out quickly, then you should have plenty of fuel for the flight back to Zero's. When I beat this mission, I ended up with a little over 1/3 of the fuel meter full.
On the bright side, it's by far the hardest mission in the game.
